Chuck Lorre is the creator of Two and a Half Men AND The Big Bang Theory; why does everyone hate him for Men BUT love him for Theory?

I hear a lot of people saying how much they despise Chuck Lorre for Two and a Half Men. To the point where they speak very derogatorily about him and boycott the show – but then they have no problem with him when he’s doing The Big Bang Theory, Dharma and Greg, Mike and Molly, or any of his other shows. So what gives?
